Writing text to a file [PHP, HTML]

Question

I want to write text to the bottom of an existing text file but don't have a clue how to do it.

I have tried the code below but it don't work. The text file location is C:\inetpub\wwwroot\test.txt

<?php

    if(isset($_POST['submit'])){
        $email = $_POST['email'];
        $file = fopen("C:\inetpub\wwwroot\test.txt\\","a+");
        fwrite($file,$email);
        fclose($file); 
        print_r(error_get_last());
    }
?>

<form action= "" method="post" name="form">
<input type="text" name="email">
<br>
<br>
<input type="submit" name="submit" value="submit"><br>
</form>

What am I doing wrong?

Do you get any errors from the PHP interpreter when running this script? Why do you have two backslashes at the end of the file path? — Kyle

The backslashes should either be doubled up (\\) to avoid escaping, or replaced with forwards slashes (/). The ones at the end look wrong too, as Kyle says. — halfer

Try

file_put_contents("file_path", your_content, FILE_APPEND);

so in your case...

<?php
    if(isset($_POST['submit'])) {
        $email = $_POST['email'];
        file_put_contents("C:\inetpub\wwwroot\test.txt", $email, FILE_APPEND);
    }
?>

Documentation here.

sorry I'm new to PHP, where exactly would that go?

See edit. It just replaces your fopen, write, and close calls.

Make sure your path is correct. Documentation for this function can be found here with examples: us2.php.net/file_put_contents

It's not working for some reason and if I was to add upload.php to the form action"" and put the php in the upload.php it goes to a white page.

<?php
if (isset($_POST['submit'])) {
  $email = $_POST['email'];
  $write = fopen('C:\inetpub\wwwroot\test.txt', 'a');
  fwrite($write, 'Email: '.$email ."\n");
  fclose($write);
}
?>

<form method="POST" name="form">
<input type="text" name="email"><br><br>
<input type="submit" name="submit" value="submit"><br>
</form>
